74ACT16541DLR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74ACT16541DLR is a 16-bit buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum quiescent current of 8 µA. The device provides high drive capability with low-level output currents up to 24 mA and high-level output currents of -24 mA. Packaged in a 48-pin SSOP (DL) format, it supports operation temperatures from -40°C to +85°C. Propagation delay is specified at 8.3 ns at 5 V, ensuring efficient signal transmission for wide-bus applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' confirms the SSOP-48 package and tape-and-reel shipping configuration. Ensure the order matches the 74ACT series requirements for 5V operation. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with distributor catalogs to validate availability and lead times before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit parallel data buffering with high drive strength. The ACT series offers faster switching speeds compared to standard ALS or LS families while maintaining CMOS power efficiency. Ensure the application environment stays within the -40°C to +85°C operating temperature range. Verify that the 4.5V to 5.5V supply voltage aligns with the system's power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' Widebus Family, designed specifically for high-density digital systems. The 74ACT series represents advanced CMOS technology, providing performance comparable to TTL but with lower power consumption. The 16-bit width makes it suitable for modern microprocessor data buses and high-speed interface circuits where signal integrity and speed are critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include other 74ACT16541 variants from different manufacturers, provided they meet the same electrical specifications. Check for equivalent packages such as SOIC-48 if SSOP is unavailable, though pin spacing differences must be accounted for. Ensure any replacement maintains the 3-state output functionality and TTL input compatibility.
